The Dukedom of Cleveland was a peerage in the Peerage of England, and later in the Peerage of the United Kingdom. The first creation was for Barbara Palmer, the mistress of King Charles II. The Dukedom of Southampton was created, along with the Earldom of Chichester and Barony of Newbury, for Charles Fitzroy, the illegitimate son of Charles and the Duchess of Cleveland. In 1709, the Duke of Southampton inherited the Dukedom of Cleveland; both dukedoms became extinct in 1774. The Dukedom of Southampton has not been created again.
The Dukedom of Cleveland was created again in 1833 for the third Earl of Darlington, along with the title Baron Raby. He was a great-grandson of Charles, Duke of Cleveland and Southampton, and had been created Marquess of Cleveland in 1827. The title became extinct again in 1891.
However, he had committed an offence in appointing four persons to relieve him of his duties as lord chancellor and advantage was taken of this to deprive him of his office in March, when he also ceased to be a member of the privy council.
Her son, Charles Fitzroy (1662-1730), was created duke of Southampton in 1675, this title becoming extinct when his son William died in May 1774.
The barony of Southampton was created in 1780 in favour of Charles Fitzroy (1737-1797), a grandson of Charles Fitzroy, 2nd duke of Grafton, he being thus, like the holders of the dukedom of Southampton, descended from Charles II.
THE title of duke was first bestowed upon Edward prince of Wales, commonly called the Black Prince, who was created by his father king Edward the third 13 March 1337 duke of the county of Cornwal, with remainder to the eldest sons of the kings of England for ever.
Thomas, son of John of Gaunt duke of Lancaster, was created by king Henry the fourth 5 July 1411 earl of Dorset, and by king Henry the fifth duke of Exeter, which titles became extinct at his death 27 December 1426.
Lodovic Stuart, duke of Lenox of the kingdom of Scotland, was created by king James the first 6 October 1612 baron Setrington and earl of Richmond, and a few years afterwards earl of Newcastle and duke of Richmond, which titles became extinct at his death 11 February 1623.
